This could be a lot of fun. Chances are it will use some proprietary codec and editing interface, thus limiting content to officially licensed movies. This proprietary nature should remain in place for about 12 hours after release thanks to the good folks of the interwebs, opening the door for massive copyright infringement and probably a lot of fun. "Witness" is cool, and my middle-age sensibility says this was some of Ford's best work, but I can think of dozens of movies I would rather act in.
From the looks of the website, they made the promo and licensed the content but they do not have an actual product yet.

You guys recall TV shows in the very early 70's called "The Copycats" or "Don Adams' Screen Test"?

Similar concept. Where these guys will make MORE money I think is if they give you backgrounds to famous live concert performances of rock bands, cash in on the Guitar Hero crowd.

Or, put up a background of a simple live TV news report, the reporter trying to intro his package, so all those idiotic people that love to jump around and wave in the background have some place else to do that...
